Tom's rear hub seals problems

Post by 250GT »

Hi Tom,
the way you descript you problem solving can function , but only for a while I think.
I had it in the past over and over again.
Now I replace the open wheelbearing for the one which is closed on one side( SKF).
All F-cars before 1960 has special not standard size bearings.
I buy standard stuff and reduce the inside ring that 1mm.
The GTE with the much beter enforced housing have also stonger axels( other diameter)
The seal now must maybe collect only 1% witch can get through the bearing.
The oil is so thick and cooled down very well with this type of housing.
As always some pics for better understanding.

its only a hobby here

Hi Cornelis,

Do you send the bearing out for machining, or do you reduce the inner dimension yourself? I'm not a machinist, so I'm curious how it's done.

Your solution sounds good, but I'm curious to see if my fix will work. SInce everything is assembled and sealed, I might as well try it out. If it fails again, I will try your approach. Since some cars have no problems with these seals and others do, I think the main variance is in the bearing carrier spacing...I think.

We'll know in a few months if this modification works!

Gary, a web friend told me to look up seals on the SKF website http://www.skf.com/portal/skf_us/home to see if there is a better seal for our application. I found a double lip seal with the same dimensions that would work. Although the second seal is more of the dust seal, it may give that little bit more sealing surface to help.

If my current solution fails, I have a couple more options.

Tom,

Iam not a machinist either,

Every prof shop or serious hobby mechanic should have a maschinist in the back.

I have a retired lathe-man witch made for me, every" difficult" bearing equipement to reduce the bearing in the right size.

Those parts have two halfs that can be screwed together, with an opening for the metal -chiser at one side .

it schould avoid rotation and protect for metalparts, whitch occur during this procedure.

He is paid in red wine and Cohibas which I adore my self ,have them always in stock.

hobby must make fun or not ?

next time I visit him will make some pics of my self invented equipment.

Its nice to become more and more indepandent in certain things, and you don't have to wait weeks to get the right stuff.

but you are familiar with this phenomenan I think.

Cornelis

P.S I dont start a production line .

Hi Cornelis,

Red wine and Cohibas can be a great form of currency!

I don't know if it's the same in Europe, but finding a good machinist locally is not an easy task! I would love to become better at my machinist skills with my home lathe, and would love to have an old timer come over and teach me how!

I found one of my drinking and smoking lathe-operator pieces at my place.
here the pics,
The "working opening" need a stong bevel to bevel the shap edges on the bearing.
Pics speaks for themself I think.
All the diff size berings need a diff basepart the second" wheel" fits on all of them
Good luck Tom with the first you made youre self.
I think the westcoast is Kerry's terretory?
